Hi Richard,
On the question of example 11, I hope my previous email [1] helped to
clarify.
Here are some comments on the other points you originally made..

We haven't discussed this in any depth in the WG.
I think advice on when to use e.g. en / en-GB / en-US is out of scope
for the SKOS Reference, which just serves to establish the data model,
and tries to defer on detailed usage guidance to the SKOS Primer and
other documents that may be developed within the community of practice
in response to implementation experience. I would hope that a best
practice could be developed and published by the community of practice
in the near future.

Example 19 is only intended to illustrate a technical feature of the
SKOS data model, which is that a resource has at most one value of
skos:prefLabel per language tag, and as "en" "en-US" and "en-GB" are
different language tags, the example is therefore consistent wrt the
SKOS data model.
The example is not intended to suggest or imply any best practices wrt
provision of labels with or without language variants. I think that is
out of scope for the SKOS Reference, and hope that detailed guidance
on how to deal with language variations could be developed more fully
in a separate note, by another WG or by the community of practice.
Also, any recommendation on how processing tools should deal with
language variants is also, IMO, out of scope for the SKOS
Reference. However, I would be more than happy to make reference to
the filtering and lookup algorithms defined in RFC4647 as possible
implementation strategies, as suggested by Addison [1]. If you have
any thoughts on how to word some prose regarding RFC4647 for the SKOS
Reference, I'd be very glad to hear them.
> There is another small issue here related to the "colour"@en declaration. Why is the American spelling used for en? What would happen if the English spelling were used in some places? Is there a stated policy that en = US English?
Just to reiterate, this example is arbitrary, and is intended only to
illustrate a technical feature of the SKOS data model. However,
because I had to choose some value for en, and because the official
language of W3C tech reports is US english, I chose the US english
spelling.
There is no stated policy that en = US english. Again, I hope that
best practices on how to choose between variants to populate labels
for primary language subtags would be dealt with by the community of
practice.
Cheers,
Alistair
